#2084

Pe o platformă sunt montate pe poziții consecutive n bare verticale de lățime 1cm. Vom presupune că platforma este mărginită față/spate de ziduri transparente de înălțime infinită. Cantitatea de apă ce poate fi reținută într-o unitate de volum (1cm x 1cm x 1cm) este de 1 litru. Determinați cantitatea de apă reținută.
